Abstract:
The shift from foraging to farming during the Neolithic transition led to a large expansion in human populations, however the parameters of these expansions in specific populations have not yet been determined. In this study, Y-chromosome data is utilized to model the demographic histories of the R1b and E1b1a Y haplogroups based on statistics measuring the “star-likeness” of tree structures from simulated and empirical data.
